I would like to add my Frames, their colony (i made it up) and the drivers to the lore. I understand that there are fanfictions, but is it practical? Like the serpent group, they are cannon, and i think they are fanmade. So how does that work?

Technically only stuff that Joshua and Soren write are canon. You would have to convince them to include whatever you have made to make it "official", and from what I know about them that's very unlikely.

But, frankly, post whatever you have written on the fanfic section for now, anyway. Nothing to lose. Things like Twanks LLC and the rest of the Budget Frame Wars are all fan-made and we don't love them any less.
